Permutation-Symmetric Multicritical Points in Random Antiferromagnetic Spin Chains [PDF]

, 2002
The low-energy properties of a system at a critical point may have additional symmetries not present in the microscopic Hamiltonian. This letter presents the theory of a class of multicritical points that provide an interesting example of this in the ...
